Two babies, two bonds: Frequency and correlates of differential maternal-infant bonding in mothers of twins.

We assessed prevalence and correlates of differential maternal-infant bonding (i.e., experiencing a stronger bond with one baby vs. the other) in mothers of twins, focusing on aspects of maternal mental health, well-being, and pregnancy/birth that have been previously linked with maternal-infant bonding. Participants (N = 108 American women, 88.89% White, 82.41% non-Hispanic, aged 18-45, who gave birth to twins in the past 6-24 weeks) were recruited from postpartum support websites. Participants completed a Qualtrics survey assessing pregnancy/birth history, symptoms of depression and anxiety, sleep, stress, romantic relationship satisfaction, and postpartum bonding. Twenty-six participants (24.07%) reported a bonding discrepancy. These participants endorsed higher symptoms of depression and anxiety, lower relationship satisfaction, lower average postpartum bonding, higher general and parenting stress, and longer pregnancy (all ps > .05). Greater degree of bonding discrepancy correlated with more depression, higher parenting stress, longer pregnancy, and lower relationship satisfaction (all ps > .05). Mothers of twins may benefit from postpartum mental health support, stress management strategies, and interventions to improve bonding. Future work should assess the role of breastfeeding difficulties, delivery method, birth-related trauma, infant regulatory capacity, and temperament. Longitudinal studies will help test cause and effect and potential long-term repercussions of maternal-infant bonding discrepancies.

Evaluamos la prevalencia y factores correlacionados del apego afectivo diferencial materno­infantil (v.g. experimentar un apego más fuerte con un bebé vs. el otro) en madres de gemelos, enfocándonos en aspectos de salud mental materna, bienestar, así como el embarazo/parto que previamente han sido relacionadas con la afectividad materno­infantil. A las participantes (N = 108 mujeres estadounidenses, 88.89% blancas, 82.41% no hispanas, de 18­45 años, que dieron a luz gemelos en las pasadas 6­24 semanas) se les reclutó de los sitios de apoyo posterior al parto en la red. Las participantes completaron una encuesta Qualtrics para evaluar el historial de embarazo/parto, los síntomas de depresión y ansiedad, el sueño, el estrés, la satisfacción con la relación romántica, así como la afectividad posterior al parto. Veintiséis participantes (24.07%) reportaron discrepancia en el apego afectivo. Estas participantes confirmaron síntomas más altos de depresión y ansiedad, más baja satisfacción en la relación, más bajo promedio de apego afectivo posterior al parto, más alto estrés general y de crianza, así como un más largo embarazo (todos los ps > .05). Un mayor grado de discrepancia en el apego afectivo se relacionó con más depresión, un más alto estrés de crianza, un más largo embarazo, así como una más baja satisfacción en la relación (todos los ps > .05). Las madres de gemelos pudieran beneficiarse de un apoyo de salud mental posterior al parto, estrategias de cómo arreglárselas con el estrés e intervenciones para mejorar el apego afectivo. El trabajo futuro debe evaluar el papel de las dificultades de amamantar, el método usado para dar a luz, el trauma relacionado con el nacimiento, la capacidad regulatoria del infante y el temperamento. Estudios longitudinales ayudarán a poner a prueba la causa y el efecto las potenciales repercusiones a largo plazo de las discrepancias en el apego afectivo materno­infantil.

Nous avons évalué la prévalence et les corrélats du lien maternel­bébé différentiel (c'est­à­dire qui font l'expérience d'un lien plus fort avec un bébé par rapport à l'autre) chez les mères de jumeaux ou jumelles, en mettant l'accent sur les aspects de la santé mentale maternelle, le bien­être et la grossesse/naissance ayant précédemment été liés au lien maternel­bébé. Les participantes (N = 108 femmes américaines, 88,89% blanches, 82,41% non­latinas, âgées de 18­45 ans, ayant donné naissance à des jumeaux ou jumelles dans les 6­24 semaines précédentes) ont été recrutées à partir de sites internet de soutien postpartum. Les participantes ont rempli un questionnaire Qualtrics évaluant la grossesse/l'histoire de la naissance, les symptômes de dépression et d'anxiété, le sommeil, le stress, la satisfaction de la relation amoureuse et le lien postpartum. Vingt­six participantes (24,07%) ont fait état d'un écart du lien. Ces participantes ont fait état de plus de symptômes de dépression et d'anxiété, d'une satisfaction avec la relation plus basse, d'un lien postpartum plus bas en moyenne, d'un stress général et parental plus élevé, et d'une grossesse plus longue (tout ps >,05). Un degré plus élevé d'écart du lien a correspondu à plus de dépression, un stress de parentage plus élevé, une grossesse plus longue et une satisfaction de la relation plus basse tous ps > ,05). Les mères de jumeaux ou jumelles peut tirer profit d'un soutien en santé mentale postpartum, de stratégies de gestion du stress, et d'interventions pour améliorer le lien. Dans le futur des recherches devraient évaluer le rôle de difficultés de l'allaitement, la méthode d'accouchement, le trauma lié à la naissance, la capacité régulatoire du bébé et son tempérament. Des études longitudinales permettront de tester la cause et l'effet et les répercussions à long terme potentielle pour les écarts dans le lien maternel­bébé.

[Pulmonary glial heterotopia: Unique lesion in an infant with anencephalic twin]. / Hétérotopie gliale pulmonaire : une lésion exceptionnelle chez un nourrisson avec un jumeau anencéphale.

Pulmonary glial heterotopia is an extremely rare entity whose pathophysiology remains unclear. We report for the first time one case of pulmonary glial heterotopia occured in a one-month baby free from any malformation. She has the particularity of being born from monozygotic monochorionic twin pregnancy where her anencephalic exencephalic sister suffered a medical termination of pregnancy. She presented neonatal respiratory distress, which recurred one month later. Chest X-ray revealed bilateral cystic pulmonary lesions mainly located in the right lung. Given the suspicion of congenital cystic adenomatoid malformation (CCAM), she underwent an upper and a lower right lung lobectomy at four months old. The pathological study found a multi-cystic lesion consisted of well-differentiated and poorly cellular glial tissue sometimes lined by bronchic epithelium. There was no pathological evidence for a CCAM. The evolution was favorable after surgery with an infant who was well five months later. This is one of the very few cases where the disease did not lead to rapid death in utero or during the perinatal period. This suggests that effective management by surgery could be a decisive factor in the survival of these patients.

[Supporting parents after the death of a premature twin]. / Accompagner les parents lors du décès d'un jumeau prématuré.

The death of a twin hospitalised in neonatal intensive care presents several issues that the children's nurse must take into account. Identifying the elements which characterise the issues around supporting families confronted at the same time with the grieving and bonding processes enables suitable actions to be put in place.

Infant twin mortality and hospitalisations after the perinatal period - a prospective cohort study from Guinea-Bissau.

OBJECTIVE: To examine mortality and hospitalisations among infant twins and singletons after the perinatal period in Guinea-Bissau. METHODS: The study was conducted from September 2009 to November 2012 by the Bandim Health Project (BHP). Newborn twins and unmatched singleton controls were included at the National Hospital Simão Mendes in the capital Bissau. Children were examined clinically at enrolment. Maternal, pregnancy and obstetric information was collected and HIV testing offered at birth. Follow-up occurred at home at 2, 6 and 12 months and through linkage with the paediatric admission register at the National Hospital. RESULTS: About 495 twins and 333 singletons were alive on day 7 after birth. In total, 36 twins and 12 singletons died during follow-up, the post-perinatal infant mortality rate being 91/1000 person-years for twins and 42/1000 for singletons (HR = 2.11, 95% CI: 1.09-4.07). In a multivariable analysis among twins only, birth weight <2000 g [3.32, (1.36-8.07)], death of the cotwin perinatally [2.54, (1.16-5.57)] and severe maternal illness during pregnancy [2.35, (1.00-5.51)] were significant risk factors for twin death. In the subgroup with available HIV status, maternal HIV infection was strongly associated with twin mortality [3.16, (1.24-8.05)]. Death occurred at home for 60% of twins and 67% of singletons. During follow-up, 90 first-time hospital admissions were registered, with similar rates observed for twins (139/1000) and singletons (143/1000) [0.97, (0.61-1.52)]. CONCLUSION: The post-perinatal infant mortality rate of twins was double that of singletons. No excess in twin hospitalisations was observed, possibly implying obstacles to hospital admission for twins in case of severe illness.

Delivery of twins : lessons learnt from the national observational prospective comparative study JUMODA / L'accouchement des femmes enceintes de jumeaux : les enseignements de l'étude nationale observationnelle prospective comparative JUMODA.

OBJECTIVES: To summerize the results of the JUMODA study (JUmeaux MODe d'Accouchement) on the planned mode of delivery of twin pregnancy and the management of second twin delivery. METHODS: JUMODA was a national observational prospective comparative study that took place between february 2014 and march 2015 in 176 french maternity units performing more than 1500 deliveries per year. Its main objectives were the comparison of neonatal and maternal morbidity according to the planned mode of delivery and the determination of the managements of second twin delivery associated with the best neonatal outcomes. To control for potential confounding factors and indication biases, statistical analyses comprized multivariate logistic regressions and matching on propensity scores. RESULTS: The JUMODA study recruited 8823 women with twin delivery at or beyond 22 weeks of gestation. For twin pregnancies with a cephalic first twin at 32 weeks of gestation and beyond, severe neonatal morbidity was higher in the planned cesarean (150/2908 (5.2 %) than in the planned vaginal delivery group (199/8922 (2.2 %), aOR 1.56, 95 % CI 1.19-2.04). Increased neonatal morbidity in the planned cesarean delivery group was explained by higher severe morbidity in neonates born preterm (aOR 1.64, 95 % CI 1.13-2.39, for deliveries between 32+0 and 34+6 weeks of gestation, aOR 2.04, 95 % CI 1.22-3.41, for deliveries between 35+0 SA and 36+6 weeks of gestation) but not in neonates born at term (aOR 1.19, 95 % CI 0.58-2.44). In comparison with planned cesarean delivery, planned vaginal delivery was not associated with increased severe neonatal morbidity in case of breech presenting first twin after 32 weeks of gestation or with decreased survival witout severe neonatal morbidity in case of delivery before 32 weeks of gestation whatever the first twin presentation. In comparison with planned vaginal delivery, planned cesarean delivery was associated with increased severe maternal morbidity only in women aged 35 and higher. Delivery of non cephalic second twin was associated with similar severe neonatal morbidity rate than delivery of cephalic second twin. Finally, in case of cephalic second twin, internal version followed by total breech extraction was associated with less cesarean for the second twin but with higher severe neonatal morbidity in case of preterm birth in comparison with pushing efforts, ocytocin perfusion and artificial rupture of membranes. CONCLUSIONS: Planned vaginal delivery is the planned mode of delivery to encourage for the majority of pregnant women with twins, whatever first twin presentation and gestational age at delivery. No management of cephalic second twin appears better than an other, its choice will rest on obstetrician preferences.

Current knowledge on the genetics of autism and propositions for future research.

Autism spectrum disorders (ASD) are a heterogeneous group of neuropsychiatric disorders characterized by problems in social communication, as well as by the presence of restricted interests, stereotyped and repetitive behaviours. In the last 40years, genetic studies have provided crucial information on the causes of ASD and its diversity. In this article, I will first review the current knowledge on the genetics of ASD and then suggest three propositions to foster research in this field. Twin and familial studies estimated the heritability of ASD to be 50%. While most of the inherited part of ASD is captured by common variants, our current knowledge on the genetics of ASD comes almost exclusively from the identification of highly penetrant de novo mutations through candidate gene or whole exome/genome sequencing studies. Approximately 10% of patients with ASD, especially those with intellectual disability, are carriers of de novo copy-number (CNV) or single nucleotide variants (SNV) affecting clinically relevant genes for ASD. Given the function of these genes, it was hypothesized that abnormal synaptic plasticity and failure of neuronal/synaptic homeostasis could increase the risk of ASD. In addition to these discoveries, three propositions coming from institutions, researchers and/or communities of patients and families can be made to foster research on ASD: (i) to use more dimensional and quantitative data than diagnostic categories; (ii) to increase data sharing and research on genetic and brain diversity in human populations; (iii) to involve patients and relatives as participants for research. Hopefully, this knowledge will lead to a better diagnosis, care and integration of individuals with ASD.

[Partial facial duplication (a rare diprosopus): Case report and review of the literature]. / Duplication faciale partielle (un diprosope rare): à propos d'un cas et revue de littérature.

INTRODUCTION: Diprosopus, or partial facial duplication, is a very rare congenital abnormality. It is a rare form of conjoined twins. Partial facial duplication may be symmetric or not and may involve the nose, the maxilla, the mandible, the palate, the tongue and the mouth. OBSERVATION: A male newborn springing from inbred parents was admitted at his first day of life for facial deformity. He presented with hypertelorism, 2 eyes, a tendency to nose duplication (flatted large nose, 2 columellae, 2 lateral nostrils separated in the midline by a third deformed hole), two mouths and a duplicated maxilla. Laboratory tests were normal. The cranio-facial CT confirmed the maxillary duplication. DISCUSSION: This type of cranio-facial duplication is a rare entity with about 35 reported cases in the literature. Our patient was similar to a rare case of living diprosopus reported by Stiehm in 1972. Diprosopus is often associated with abnormalities of the gastrointestinal tract, the central nervous system, the cardiovascular and respiratory systems and with a high incidence of cleft lip and palate. Surgical treatment consists in the resection of the duplicated components.

[Medical care and perinatal health in twin pregnancies: situation in 2010 and recent trends in France]. / Prise en charge et santé périnatale en cas de grossesse gémellaire : situation en 2010 et évolution récente en France.

OBJECTIVE: To compare medical care and health status of twins and singletons in 2010 and to describe the trends between 1995 and 2010 in metropolitan France. POPULATIONS AND METHODS: Data were derived from the national perinatal surveys from 1995 to 2010, on representative samples of births, and included 14,460 singletons and 440 twins in 2010. We compared prenatal care, childbirth and health status of children between twin and singleton pregnancies and between years. RESULTS: In 2010, mothers of twins had more intensive medical care than mothers of singletons. The preterm birth rate was higher (42.7% versus 6.3%). The medical care of twins has increased (for example 51% of women had 11 or more prenatal visits in 2010 versus 26% in 1995), often following the same trends as singletons. The proportion of non-spontaneous labors increased between 1998 and 2003. The cesarean section rate increased from 42.2% in 1995 to 54.8% in 2010 among twins, and from 15.2% to 19.9% among singletons. The preterm birth did not increase, but the proportion of twins born at 39 weeks of gestation or more declined significantly. CONCLUSION: Medical care takes into account the high risks of twin pregnancies. Twins are still a medical cause for concern because of their continued increase.

[Birth weight discordance in dichorionic twins: diagnosis, obstetrical and neonatal prognosis]. / Discordance des poids de naissance des jumeaux bichoriaux : diagnostic, pronostic obstétrical et néonatal.

OBJECTIVE: To describe neonatal and obstetrical prognosis in dichorionic (DC) twins with a birth weight discordance under 20% and evaluate the influence of intrauterine growth restriction on the management. PATIENTS AND METHODS: We studied retrospectively 67 DC twins birth between July 2002 and July 2012 at our university labour ward. Birth weight discordance was considered slight between 20-25%, moderate between 25-30%, and severe over 30%. RESULTS: Prevalence of birth weight discordance in DC twins is estimated at 11.4% in our study. Eighty percent of severe discordance was diagnosed before delivery, 41% for moderate discordance and 20% for slight discordance. We note 30% of pre eclampsia in our population with 44% in the severe discordance group. Mean gestational age was 35.1 weeks for slight and moderate discordances, and 33 weeks for severe discordance. Caesarean section rate was 48% for severe discordance and only 36% for slight discordance. Vaginal delivery rate is 56.7%. More than half of patient with a severe discordance gave birth vaginally. Intrauterine growth restriction rate under the 10th percentile was 18.7%. Prevalence of IUGR was 24% in sever discordance group, 23.5% in the moderate discordance group and 10% in the slight group. Neonatal morbidity rate was 20.8% mainly in children with IUGR. DISCUSSION AND CONCLUSION: Neonatal mortality and morbidity rate are mainly increased in severe discordant twins. These pregnancies are at high risk of maternal morbidity. Vaginal delivery must be preferred for slight and moderate discordances. In case of severe discordance, vaginal delivery should be considered depending on the degree of intrauterine growth retardation.

Etude comparative du vécu psychique de femmes vivant une grossesse gémellaire ou unique / Comparative study of the psychological experience of women carrying a twin or a singleton pregnancy / Estudo comparativo da experiência psicológica de mulheres grávidas de gêmeos ou de um único bebê

Quelle incidence de porter deux enfants sur l'expérience psychique des femmes ? Dans cette étude qualitative et comparative, nous avons rencontré dix femmes enceintes: trois de jumeaux de même sexe, trois de jumeaux de sexe différent et quatre d'un enfant unique. Elles ont répondu à un entretien semi-directif, à une échelle de représentations sémantique-différentielle et réalisé deux dessins. Les résultats montrent l'intérêt de favoriser les échanges entre les femmes enceintes de jumeaux, afin de faciliter leurs identifications et de les rassurer sur leurs compétences maternelles. Ils soulignent aussi la nécessité de proposer un espace pour que les femmes enceintes de jumeaux de même sexe, notamment, puissent verbaliser leurs peurs et leurs fantasmes concernant leurs enfants et la relation gémellaire qu'ils pourraient entretenir.

What is the impact of carrying two fetuses on the psychological experience of women? In this qualitative comparative study, ten women have been met: three were expecting samesex twins, three were expecting sex-different twins, and four women were carrying a singleton pregnancy. They responded to a semi-structured interview and to a semantic-differential maternal representations scale, and have drawn two pictures. The results underscore the need of encourage women expecting twins to discuss with other women experiencing the same situation in order to facilitate their identification processes and to support their maternal sense of competence. In particular, it's important to offer women expecting same-sex twins the opportunity to verbalize their fears and projections regarding their fetuses and their future twin relationship.

Qual é o impacto de esperar gêmeos para a experiência psicológica da mulher grávida? Neste estudo qualitativo e comparativo, dez mulheres grávidas foram encontradas: 3 grávidas de gêmeos do mesmo sexo, 3 de gêmeos de sexo diferente e 4 esperando um único bebê. As mulheres responderam a uma entrevista semidiretiva e a uma escala semântica-diferencial de representações maternas, e realizaram dois desenhos. Os resultados mostram a importância de se favorecer as trocas entre mulheres grávidas de gêmeos para facilitar seus processos de identificação e tranquilizá-las quanto às suas competências maternas. Afirmam também a necessidade de proporcionar um espaço, sobretudo para mulheres esperando gêmeos do mesmo sexo, para que possam verbalizar seus medos e fantasias com respeito aos seus filhos e à relação gemelar que poderão estabelecer.
